1 '0 all whom it may concern:

lie it known that l, lVAnnnN C. Runs, a citizen of the United States, residing at Sinner-ville, in the county of Middlesex and State of lrlassachusetts, have invented new and useful Improvements lVaterCloset-s, of which the following is a specification.

T he present invention relates to seats for water closets provided with means'for automatically furnishing a clean and fresh surface for each use. Appliances or machines of this nature have been shown in prior patents of the United States obtained by myself and also by Stanley Etherington jointly with. myself. numbered 1,092,391

April 7. 1914; 1,092,392 April 7, 1914:; 1,156,175 October 12, 1915; 1,165,123 December 21, 1915 and 1,1715% February 15,-

191.6. In all these devices the clean surface of the seat is furnished by a sheet or strip of paper which is fed. by automatic means with each use of the fixture so as to remove that part of the paper which covered the seat at the time of a previous use and to place an unused. portion of the paper upon the seat for the next user.

The object of the present invention is, in general. to provide improvements in machines of the type indicated, which have been shown by experience to be desirable. and in connection therewith to secure all the useful and desirable effects of the previous machines by simplified means, thus furnishing a machine which is less expensive to construct and at the same time aecom pl'ishes all the desired results. Among the particular objects included within the foregoing general statement are the following: to provide a more effective, and at the same time a simpler. means to prevent overfeed of the paper with consequent looseness or slack between the supply and take-up members of the paper strip, which. maintains the paper in a smooth stretched condition while at the same time permitting the paper to slide upon the seat with movements of the occupant; to provide an oscillating means for projecting and withdrawing the seat: to combine such a means with a housing in which the seat is contained and by which it is protected when not in use; to inclose within the housing all parts which can be thus inclosed, reducing the number in Sanitary of exposed movable partsto the irreducible minimum; to diminish as far as possible the number of elements requiring a preservative or ornamental finish, and to make such parts .as are exposed and require such finish of a character enabling them to be easily cleaned; and to provide other improvements which are set forth in detail in the following specification. The invention comprises the means and instru mentalities for accomplishing the foregoand the after mentioned objects, described in the following specification and illustratedin the drawings which form a part thereof, together with all modifications and equivalents of such means em-' braced within the scope of the appended claims.

In the drawings, Figure 1 is a front elevation, with a part broken away and shown in section, of a machine or apparatus embodying my present invention.

The same reference characters indicate the same parts in all the figures.

As in the prior patents referred to, the

entire machine or fixturecomprises two sections, duplicates of one another, eachem bodying one seat member, supply and takeup means for the paper covering sheet,

the seats of tlietimparts of the machine may be projected tmvard one another from opposite sides of the fixture. In this speclfication I will describe in detail the elements of the left" hand section or part of the apparatus, making it understood that other part is exactly the same.

A w ater closet bowl or equivalent fixture is shown in outline in Figs. 1- and 5 and is designated by the numeral 8. V The machine embodying. the invention comprises two casings 9, 9 which occupy positions close to opposite sides of the fixture 8, each having a supporting leg lO at its forward end, and a crossbar 11 connecting the rearends of the casingsand extending over the rear part ofthe fixture' 8 so as to rest thereon.- This bar is secu-redby bolts 11 (F 1g. 5)

the shanks of whichpass through holes al v ready provided in the commoniorms of closet bowls, and the heads of whichare contained in a T slot 11" in the under side of the bar, the cent al partjof such slot having an enlargement 11 through which such heads maybe inserted; this arrangement causing the bolt heads to be protected and covered, and leaving the bar with .an uninterrupted smooth upper suri'ace capable of being easily cleaned. One feature of the "invention comprises a means for adjusting thelength of the leg 10 so that the machine may be adapted to fixtures of (different heights. For this purpose the leg 10 .is containedin a telescopic manner in a sleeve 12 projecting downward from the casing, and the end within the sleeve is partly cut away at one side as shown by dotted lines in Fig. 41-, so as to make a shoulder13. A pin let extends across theinterior of the sleeve and is adapted to rest either on the end-0t the leg, orron the 'shoulder13, the leg being movable ()IldWlSGfll'ld also rotatably for this purpose. The-drawing shows the pin 14 as resting on the end of the leg, in a depresslon 15 (Fig. to preventthe leg being accidentally turned soas to let the casing.

down unintentionally. V

There is an addltlonal connection between the casings in the form of a tubelG passing 7 under the forward part of the fixture 8, its ends being threaded intothe adjacent sides of the casings, as shown in Fig. 3, by oppo sitely inclined threads. A on the tube to abut against the casings, Theyserve as abutments, lock nuts, and covers for the ends of the threads in the sleeve, for they extendbeyond the threads,

the

Nuts 17 are screwed" the outer surface of the tube, providing close joints which exclude'w'ater, dust, and

otherforeign matter fronr'the' threads. In

additionto being a connector, the tube 16 is also ahousing for certain transmission shafts later described.

The casing 9, which'is open atthe top, is provided with a detachable cover 18 having flanges at its ends and outer edgeto embrace the walls of the c sing, and is equipped with leaf springs 19 near its ends which bear against lugs or stops 20 which project inward from the opposite end walls of the casing. Books 21 projecting in- V wardly from the outer wall of the casing are engaged with straps 22 which are secured to lugs 23 of the'cover, each of these straps having an eye through whiclrone of the hooks passes. lVebs or ribs 24 project down from the under side of the cover near its endsand their lower edgeshave cam functionspresently described. The hooks and straps anchor the cover and at the same time act as hinges permitting its inner part to be' raised and lowered in a manner later dcscribedr These straps permit removal .of r

the cover when necessary to replace a fresh paper strip for a used strip, but are of such character that tlns removal may be effected only byauthorized persons, who are acquainted with, the internal structure, and is made impossiblezto meddlesome persons.

Inside the casing is a frame composed of two end bars 25, 26and a connecting bar 27, whicl'r may be made a-ll in one piece, it deshed, and is provided to enable all of the operating parts to be assembledioutside oi' the casing and then inserted as a unit, for

the space within the casing, is so restricted as to make itextremely diilicult, if not impossible, to assemble all the working'parts therein in the first instance. \Vhen inserted, the connecting bar extends along the bottom of the casing and is secured by sc1'ews28, while the end bars extend parallel to but separated from the end walls of the casing and made fast to angular brackets 29 which are secured to the outer wall or" the casing. This frame provides bearings for a rock shaft 31, asupply spool 32 and a take up'spool 33 On the ends of the rock shaft 31 between'the frame and thecasing walls are arms 34 and 35, the upper ends of which are offset inwardly and carry antifriction rolls 36. which bear against the under surface of thewcbs 24 011 the cover. v'llheseat 37 is carried by these arms. .The part here called a seat is so designated because it is the element of the device on which the user sits. Each of the duplicate parts of the apparatusincludes one of these members, each being adapted to be projected from within its casing toward the center line of the toilet fixture, as later described and as shown in lfiigs. E2 and 8. Then the seats are projected from both casings they leave a sufficiently wide space between them extending from front to rear, but are at the same time near enough together to support the occupant comfortably. In the embodiment of the invention here shown the cooperation of both seat elements is necessary to give complete support to the occupant; but as it is within my contemplation to combine the principles o f the invention with a seat such as that shown in Fig. i. of my Patent No. 1,165,123 of December 21, 1915, which is a unit in construction and operation, furnishing the entire support for the occupant, and as the part identified by the numeral 37 is typical of any sort of seat which might be used, I prefer to call it by the term seat, rather than by any other term. Preferably the main part of the seat is made of a piece of wood, to the ends of which are connected bars 38, 39 which cross the operating arms 34-. and 35 respectively and are connected thereto by the pivots on which the rolls 36 are mounted; the bar 38 being thus connccted to arm 34, and bar 39 to arm 35. A convenient means of connecting said bars to the seat is shown in Fig. 5. The body of the seat is recessed at its ends, permitting its upper surface to extend over the bars, the latter being set into these recesses. Each bar is secured by a bolt d0 passing into the seat and engaged at'its inner end with a nut d1 which is set into a pocket formed in the under side of the seat. The seat extends from the arms toward an opening l9. in the inner wall 43 of the casing, but is entirely inclosed within the casing and its cover when in the normal position. By swinging the arms 84L, 35 inwardly the seat is projected through this opening and over the toilet fixture. The forward extremity of the seat carries a roll 4A, around which the paper covering passes, such roll being rotatable in order to reduce the friction of the paper being drawn around the seat. This roll is set into the forward edge of the seat but extends somewhat beyond the parts of the seat adjacent to its opposite ends, whereby it holds the edges of the paper, which is somewhat wider than the length of the roll and is substantially of the same width as the seat from front to rear, out of contact with those parts of the seat edge. Each of the seat bars 38 and 39 has an extension 45 passing beyond the adjacent arm, and to which is connected a retractile spring 46, also connected to the arm (34, 35, respectively), tending always to elevate the inner or forward edge of the seat and depress the extension. On the latter is an outwardly projectin lug 47 which is adapted to pass under and co-act with the lug 20 when the seat is in position of use as shown in Fig. 3.

A spring i8 is coiled around the rock shaft 31., and one end of it is attached to engage with a pin 18 set in this rock shaft while the other end. is engaged with the frame. This spring tends to withdraw the seat until the arm extensions &5 bring up against the outer wall of the casing.

For the purposes of this description the .ll'lIlS 34; and 35, with the rock shaft to which they are rigidly secured, may be con sidered as a seat carrying swing frame which is adapted to be oscillated for pro 'jceting and withdrawing the seat. The withdrawing motion of the swing frame is caused. by the spring 48 already mentioned. The seat projecting oscillation is accom-- plished by an arm 41) attached to the forward arm 34 of the swing frame by a screw or stud 50, but extending beyond said forward arm and carrying a stud 51 which bears on the outer side thereof to give a suf iicient purchase thereon. The under edge of such bar is recessed to receive and rest on the hub portion. 3a? of the swing arm, such recess affording a third point of engagement with the swing frame and giving an additional point of application of force. This operating arm extends through an opening 52 in the casing and crosses a similar arm 19 which operates the corresponding swing fran e in the other casing. Suspension rods 53, are hung from the ends of these operating arms and carry a treadle by means of nuts 55 which are adjustable to alter the distance of the treadle from the floor and so determine accurately the limits of movement capable of being given by the treadle to the seat. The limit thus given to such movement by arrest of the treadle against the floor avoids over-strain of any of the parts by excessive force applied to the treadle. 56 represents a cushion stop of soft or yielding material, such as rubber, cork, etc, on the under side of t 1e treadle bar which is adapted to strike the floor with cushioning effect when said bar is depressed. as shown in Fig. 2.

T he paper P which covers the scat passes from the supply spool 5-32 across a yielding tension roll 57, over a guide roll 58 journaled in bra kets 1) on the inner wall of the casing, around the roll M- on the inner edge of the scat, over the top of the seat, around a guide roll 60 jonrnaled in brackets 61 (Fig. 2) on the outer wall of the casing, and thence to the take-up spool 33. The tension roll 57 is journaled at its ends in arms 62 which are connected by pivots (53 with the side bars 25 and 26, respectively, of the frame, ant. are engaged with springs 64L (Fig.1) which hold the roll so as to bear on the paper i between the sup my spool and the guide 58. fr u' icient paper to fur" nish a fresh covering for the seat d awn off from the supply spool by the plunger action of the used, paper is hen up when the seat is r tractechby the t operated to that e 1 y attention'being particularly directed to the large scale Figs. 8 and 9. v

In the axial line of the take-up spool is a shaft h! whereon is pinned a pinion (35 and an arm (5 H carrying a pawl 642. Loosely mounted on said shaft is a ratchet wheel 6433 and between the latter and the arm 64:]. is a collar (54.4 formed integral'with, or-otherwise securely attached to the shaft. The pinion meshes with an internal gear segment 66 which ispivoted on a part of the fixed frame by means of a rock shaft 6?, to which there is connected an arm (SShaving anotch 69 receiving and embracing a stud 70 on the adjacent arm 35 of the swing frame. The head 71 of the take-up spool is mechanically separate from the shank of the spool and is supported on the shaft 6% so that it may turn thereon. 0n theinner end of this shaft is a washer 64:? which overlaps seat when projected, and the Lil t by the following means,

. the inner face of such head and is retained by the head of a screw 648. The rim of head Tl lS provid ed with ratchet teeth 72 coacting with pawl 73 pivoted to the frame in a fixed location. Said pawl 78 permits rotation of the spool in the winding up direction but prevents rotation in the unwinding direction. Between the ratchet wheel 643 and the head 71 is a friction clutch composed of spring arms 74 attached to the ratchet wheel andpres'sing against the outer face of the head. The head is thus confined between the spring arms and the washer 64c? so that a considerable frictional resistance is opposed to rotation of either the ratchet 6&3

or the head 71 relatively to the other. A certain amount of lateral oscillative play is permitted between the ratchet wheel and the collar 644i because the bore of the ratchet is larger than theshaft, and the collar has a spherical zone 6&5 bearing in'a complemental recess in the ratchet, so that said spring arms are able to bear equally upon the spool head in case the latter should not be exactly parallel to the ratchet. when the seat is projected, the take-up spool is heldstationary andthe pawl Gl-Q'is carried over the ratchet 643 but on the return of the seat into the casing, said pawl mov .ing in the opposite direction rotates the ratchet and so turns the spool to wind up the paper so released, the friction clutch slipping when all the slack of the paperfis taken up because of the excess angular motion given to it in order to insure complete take up of the paper and suliieiently tight winding thereof on the spoohas well when a new sheet is applied and the spool is empty, as when the spool has become many windings of the paper thereon.

Theusual tendency of persons operating ake-up spool 33, which is Thus enlarged by the mechanism is to apply the. pressure suddenly tothefootpiece, which causes the seat to be suddenly projected and to apply a powerful pull on the paper, the effect of which would be to set the supply roll in such rapid rotation that its momentum would cause it to continue turning after the seat had come to 1'est,;and thus to un roll more paper than needed, if no means were provided to checksuch action. Where such action occurs an oversupply of the paper is provided which causes it to hang loose inside or outside of the case and defeats to a greateror less extentcthe object of insuring fresh clean stretch of paper N heads and centeredby hubs 7 7 on the inner faces of the heads, which enter the ends of the tube. The'ends of the paper rollabut against the heads, as shown in Fig. 4, but

the tube doesnot so abut because the head 5 is recessed in line with the tube. The head 75 has a trunnion 7 8 which ismade fast by a setscrew 79 inplate 8O fixed to and forming a part of the frame 25, 26, 27. The other head TS-has a trunnion 81 passing through a bearing 82 in the frame member 25, in which it may turn. and also move endwisewith complete freedom. It is pressed against the end of the roll of paper and of the tube by a spring 83 which reacts against theframe'member 25. The paper is thus confined at the ends of the roll between the heads, one of which presses upon it,'and against the other of which it is pressed. One of the heads being fixed, exerts a constant frictional drag resisting rotation of the roll. This is a feature of much importance, for which I claim adequate protection, because it performs the important function of resisting rotation of the roll with a force which remains in approximatelythe same ratio to the force tendingto cause continued rotation of the roll as-the mass of thelatter 1s rliminished by withdrawal of successive quantities of paper therefrom. ,When the roll is fulhits diameter and area of contact with the stationary head being relatively large, the friction drag is relatively light; but as its diameter is reduced by withdrawalof paper and the friction contact area correspondingly reduced, while being pressed by spring 83 always with the same total force against the stationary head,

the friction drag becomes greater at the same time that the roll is more rapidly ro tateiil in delivering the same length of paper, and in nearly the same proportion. 'Thus the station. .-v head provides an effective brake pie-re ng over supply of paper under ail conditions, whether the roll is filled or is much depleted, and without imposing ex- ('essive resistance at any time.

.Yhen the takeup spool becomes filled and the supply spool empty, both may be removed and new ones substituted. In removing and substituting the supply spool the head '76 is pushed back against the spring 83; while to do the same thing with the take-up spool, a sliding keeper- 84, (Figs. 4-, 1.9, and 11) which eml. races and slides lengthwise of the member 25, is shifted along the frame member 25 to clear the trunnion "of the take-up spool shaft 85, which permits the latter to be removed. In one side of the member 25 is a notch 251 receiving said trunnion, while the keeper has an intersecting notch 84:1 to slip over the trunnion and lock it in place. One head, 86, for this roll is fixed on the shaft 85, while the other head, 71, remains in place by reason. oi its association already described. There is connected to head 71 a plate 87 having an opening into which the extremity S8 of the sh aft 85 may be screwed. 'lhe i-orres mnding shafts in the mechanisms at opposite sides oi the bowl, while otherwise alike, are oppositely threaded because they rotate in relatively opposite directions at the same time. key 89 (Fig. projects from one side of a hub on the inner tare of the head? 1, through a notch in the adj cent end of the take-up spool 33 which compels the spool to turn with this head.

The tension roll 57 is yieldingly pressed against the paper strip for the purpose of taking up any slack which may be made by the once pant ot the seat shitting his position and thereby so moving the paper as to draw more oi it from the supply roll. \Vheu the paper thus drawn released, the tension rolltakes up the slac and keeps it From being creased. or wrinkled on the seat.

it will be seen from Figs. 2 and 3 that when the seat is projected, the part of its surface next to the cover is at a higher level than. the latter. This is to insure that the occupant will sit only on the seat and that no part oi? his person will come in contact with the adj acentcasing, whichis not pro tccted by a renewable sheet. Therefore the seat is designed. so that its paper covered surface is well above the bars which attach it to the swinging frame, and the casing is so designed. that the cover lies close against these bars. It becomes necessary therefore to raise the cover when the seat is retracted, and to lower it when the seat is projected,

and this ofiice is performedby the; swing frame through the rolls 36 carried by the arms thereof rolling against the under edge of the webs-24; "In returning from the position shown'in Fig. 2 to that shown in Fig. 1, each roll-.first strikes the steeplyinclined edge 90 of the adjacent web, suddenly raising the cover enough to. admit the outer edge of the seat, and then rolls "along the gently inclined edge .91 holding the cover at a sufficient height to permit complete inclusion oi the seat. At this time the straps 22 act as hinges, about the point of engagement of which with the hooks 21 the cover swings. The springs 19, which largely balance the weightoi' the cover, aid in raising it at this time and. so diminish the work required for this purpose of the spring 48, whiclris then movingthe spring frame.

It is necessary that the seat should be retained in projected position until-the user. sits on it, and that. thereafter it should likewise be so held until the occupant ises, but then it should automatically withdraw, to prevent a second use without shifting the paper, because a complete back and forth movement of the seat is necessary to feed the paper in the required way.

These purposes are served. by a projection or latch pin 92 (Figs. 6 and ii") on the swing frame arm 34-, a latch 93, the blocks 20 and the lugs it? previously described. The latch 93 is mounted by a pivot 9% on a block 95 projecting from the inner wall 43 ot the casing in position to ride over and fall back outside of the projection 92 when the swing frame arrives at the end of its swing. This holds the seat in the position shown in Fig. 2 and by the solid lines in Fig. 6. At this time the lug l? on the extension 45 of the seat passes under the block 20 and beyond a shoulder 96, but under a shoulder 97, both on said block. The seat extension has a hook 98 which passes under a finger 99 on the latch. The spring lG at this time holds the hook 98 against the adjacent arm 3-4; and limits the elevation of the seat. l/Vhen. the seat is sat upon it is depressed into the position shown by broken linesin Fig. 6, and the lug T7 is thereby raised up in trout of the shoulder 96 and against the stop shoulder 97, which affords a positive abutment, at the same time a part of the arm 38 at the opposite side of its pivot is moved down on. a part 95 oi the block 95, thus relieving the pivot otstrain; At the same time the hook -98 releases latch 93, so that the thing which prevents retraction of the seat is now the shoulder 96. When the latch is thus raised, a stud 100 carried by a flat spring 101 attached to the latch travels along the side of a plate 102, against which it is pressed by said spring, until it rises above the edge of the plate and snaps over this edge. Theplate is secured to the arm 34,.and itsupperaedgerthus holds thelilatch above the stop pino92, so that :even when 7 the seat is released, the latch'will not again enables the .spring48lto withdraw it.

-Each of the: seats thus 'described'in detail provides onlyhalf of the support for the person usingthetoilet, wherefore it is necessary that-both seats should remain projected until the occupant has risen and that neither should be Withdrawnin case the occupant should so shift his position as to ,relieve one of-them ofany part of this weight. It is also necessary that both seats should be withdrawn when the occupant wholly rises. To secure these results I connect the swinging frames in the two casings by a tubular shaft 103 which passes through the housing 16v and carries a pinion 1 04 on each-of its ends-meshingwith a complementalpinionl05 on the rock shaft 31 of each swing frame, thus gearing said frames together so that neither can move'-independently of the other, andalso I connect the latches 93 for the two swing frames together. The means for making this last connection consistsof a shaft 106 which passes'through the tubular shaft 103 and through the pinions 104 on each end thereof, in which it has bearings, and carries an arm 107 on each of its ends. Each arm is connected by a link 10S witlran arm 109 which is connected to or formed as a part of thelatch 93, and is constantly pulled upon by a spring 110 attached .tol casing wall 43. Preferably said latch, the arm 109, and the finger 99 are all parts of a single bell crank lever. It will be appreciated that the shaft 103 with the gearing 104 and 105 at opposite ends thereof causes both' swing frames to move in unison and prevents either from moving independeutly of the other; and that the shaft 106 with? the arms 107 and links 108 attached to opposite ends of the shaft and engaged with the: latches in both casings, causes I both latches to be disengaged in unison, even though the person using theapparatus should rest upon only one of the seats, and thus insures that both willbereleased and will be in condition for a simultaneous retraction whenithe occupant rises.

The operation of themachine thus described'is as follows: The person desiring to use the toilet places his foot on the treadle and depresses it, thus,:through the-arms 49, 49 swinging the swing frames in the two casings 9 in unison toward thecenter of the fixture, andprojecting the two compleniental sets37. The rolls 36 travel-under the webs 24 in contact with the edges 91,. and when they reach the ends of these edges, the inclines 9O permit the covers to descend'below the seat surfaces. As the seat thrusts forward, it draws enough of the paper fromth'e supply spool to form a cleanunused surface, since the supply spool is free to turn and the take-up spool gagement of the latter by the pin with swing frame arm35, and turns pinion 65, which swings arm 641 carrying pawl 642 V partly around the ratchet 643-without rotating the latter, which is held stationary by its frictional engagement with the collar 644 and the friction of the spring clutch arms "4 against the spool head 71 and at the end of the movement, catch 92 on swing frame arm 34 is caught by latch 93, which holds the seat projected. The parts are then in the position shown in Fig. Qand by full lines in Fig, 6: Now when the user sits on the seat, the latter is depressed, as shown in Fig. 3 and by brokenlines in Fig. 6, until lugs 47 of arms 4-5 projecting from opposite endsof the seat bring up against abutment shoulders 97 of the stops 20, said lugs having previously been carried clear of the shoulders96. This depression of the seat and rise of arm 45 has caused the hook 98 to liftlatch 93 clear of latch pin 92 and to engage pin100, carried by the latch, with the upper edge of plate 102 which holds the latch out of engagement, leavingqshoulders 96-alone to prevent retraction ofthe seat.

lVhen the occupant rises, springs 46 raise the seat and withdraw lugs 47 below shoulders 96, whereupon the springs 48 in the two casings operate simultaneously to withdraw both seats within their respective cas ings; the gearing 105, 104 and shaft 103 causing them to move in complete unison. In thus: withdrawing, the rolls 36 associated with each seat, bearing on the inclines 90, raise the casing cover farenough to admit the seat, and then, contacting with the edges 91 hold thecovers raised to the same extent. And at the same time, the gear segment 66 rotates the take-up spool through the pinion 65,pawl 642, ratchet 643 and,

friction clutch 74 to wind up the paper released by withdrawal of the seat. In case the occupant should have rested his weight exclusively on one of the seats only, the latch 93 holding the other seat projected would have been released by the link 108, and arm 107 associated with the seat sat upon, the shaft 106, and the corresponding arm and link connected with the latch of the other seat.

ll hat I claim and Letters Patent is:

1. The combination with 'a water closet bowl of a seat, a swinging frame carrying said seat movable to project the same over desire to secure by and. withdraw it fromsaid bowl substan- I and a housing beside said bowl. within'which the seat is. inclosed when thus withdrawn;

lhecombination with a water closet bowl of a swinging framev mounted beside the same adapted to swing toward and away from the same, a seat carried by said frame movable thereby substantially in an are about the axis of said frame, over and aside from said bowl, a covering strip passing over said seat, means for causing the seat when projected to draw a fresh portion of said strip over its surface, and means for taking up that portion of the strip which was previously 011 the surface of the seat when the seat is withdrawn.
